The SYDFE1-2X/071R-PSC92KC5-0000-A0X0XXX module is manufactured by Bosch Rexroth for the SYD Hydraulic Control Systems series. It combines an axial piston variable-displacement unit with electric feedback to enable pressure- and flow-controlled hydraulic automation. A displacement of 71 cm³ defines the fluid volume moved per revolution, and clockwise rotation sets the proper mounting orientation. A cylindrical drive shaft with a DIN 6885 fitting key delivers secure torque transfer to the prime mover. The SAE two-hole flange with a 127 mm pitch allows direct connection to standard pump housings, while ports that follow SAE sizes and use metric mounting threads simplify hose selection. Mineral oil in the HL or HLP classes is the required hydraulic fluid to maintain seal compatibility. Continuous operation can begin at 250 rpm, the highest speed permitted at full displacement is 2200 rpm, and reducing displacement raises the speed limit to 2600 rpm to widen the control range without cavitation.
At 1500 rpm and maximum displacement the pump supplies 107 l/min to establish a baseline for system sizing; at the nominal speed it can deliver 156 l/min for peak demand. A maximum operating pressure of 280 bar equips the unit for circuits that require high force. Under this pressure it develops 316 Nm of torque, allowing accurate motor selection. Shaft power reaches 50 kW at 1500 rpm and climbs to 73 kW at nominal speed, so the electric drive must match these load points. An allowable axial force of 2400 N protects bearings when external belt or gear loads are applied. Together these ratings define the performance envelope needed to implement closed-loop pressure or displacement control in automated hydraulic machinery.
